Nothing serious here today

Today is the operative word: we check Seal every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

verify

verify_evidence_pack

Verify a review pack receipt by receipt. Each verdict comes from the signed envelope itself, never from stored state, and results are per-receipt, never an average.

verify_receipt

Check that a record still says what was signed: the permitted or refused decision, unchanged, under a trusted or embedded key. Handles both formats: ATTESTATION-v1 (a model-call decision) and ACTION-v1 (an agent tool action). No Aqta service in the check.

decode

decode_receipt

Read a receipt field by field, with stated limits. Does not check the signature.

explain

explain_attestation_format

The receipt format: fields, outcomes, verification commands, and what a signature does not establish. Use before describing the format.

public

get_public_key

Fetch the published Seal signing key.

receipts

list_my_receipts

List your workspace receipts filtered by outcome, policy, model, or date range. Requires your aqta_ key as Bearer.

review

get_review_pack

The published sample evidence pack: fixed review question, bound receipts, disclosure.

sample

get_sample_receipt

A genuine signed receipt from the sample workspace (demo key), for trying verification.

transparency

get_transparency_proof

Inclusion proof plus signed tree head for one of your receipts. Requires your aqta_ key.

workspace

workspace_summary

Outcome, model and policy counts across your recent receipts. Requires your aqta_ key.

Seal — questions

Answers built from our own checks of this server.

What can Seal do?

It exposes 10 tools, read directly from the server on our last check. Among them: decode_receipt, explain_attestation_format, get_public_key, get_review_pack, get_sample_receipt, get_transparency_proof and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Seal working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 390 ms. The bar chart above shows every period we have measured.

How do I connect Seal?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Seal need an API key?

No. Seal completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Seal?

It answers our handshake in 390 ms on average, which is faster than 46% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
